@UNITED STATES PATENT caries T001111 PDWDER REGEPTACLE WI'LH RESHJI'ENTPOWDER 'EiTECTOR Teofil Bonkowski; Los Angeles, flalif. .appiicecqnnovember 23, 1944, S rial N! 56.43198 9 Glaims. (01. $22-$41) dispensed, whereby more or less consistently -metered amounts are obtained.

As employed herein, the terms related "to and deriving from the word, "powder, are :to be interpreted broadly enoughto include, outside of pul- "verous' substances like toothpowder, -face *ta-lcum and otherwise, also granular substances, such as,

for example, cube cut tobacco and otherwise.

In the course of examining this specification and accompanying drawings, there are additiona1 objects and advantages that will disclose themselves.

J'Referring'to thedrawings'the .=neceptacle that -;emhodies :the instant invention %is:seen1t0 :main'ly consist, on one hand, rof :the :tubular (body 2H, whose :main section is indicated loy I- l-A, -and "whose closure-engaging end section is indicated by l I B, and, :on :the other hand, of the closure =il' z 3which is adjoimnglyaemhraced byend section 2, HB, and is partly therewithin coaxial-ly slidable into a relationship of full extension, corresponding to Figures 1 and *2, into an intermediate rela- 'tionship corresponding to Figures 3 and 4;, and into fully retracted position corresponding to Figures *5 and 6.

The lateral wall of end section 1 il B, specifically of the attenuated ,or neck :portion is thereof, is provided with the aperture 1-3, and the lateral wall of the closure is provided with the opening 44, which two holes are in longitudinal alinement with one another, but in transverse misa-linernent with one another when the end section and the closure are in the two said extreme relationsl iips, (see ,Figures 1,2, '5 and 6) at which time their;- terior of the receptacle is substantially isolated from the exterior thereof and the contents cannot 'be discharged therefrom. When, however, the end. section and the closure arein said inter- ;mediate relationship (see Figures ,3 and 4 said 'two holes are in transverse alinernent, with ,one another, and since they ,are always inicngitudinal alinement, they are now in axial or substantially complete al'inement and now constitute a joint -1oa.s aae, referred to here n y the Ii3 -4, be w e the interior and the exte io o th r c ptacle, thr ug wh ch a limit d or ea tial ,massof a total or originalinass p powder, not shown but conceivabl present insideoflth receptacle, can now be idi chargedreach ;time :that the described parts a e disposed in said intermediate relationship.

Since however each relatively small uantity dispensed, in the case of most-kind of substan e that are indicated for therecepta le, in omci n y ca k-flowing to guarantee h complet dischar hereof, a gravityupplementing,t nelling means must be provided 1 1 0 he sforcible expulsioniof said limited mass when the-two holes ere ,coaxially alined. gravity-supp ementing mean in ludes the primary expelling means or curved plate ,ofresilientmaterial L5,, conceiw ably of spring steel, secured by anyisuitablemeans to any convenient rent of ,bod-y i .In the instant mbodimen the plate is se ured by it me to a wall of endse tion 1MB of b d-yJ ,.a1.thooeh :it may be secured to a wall of the ,mainsection 11A instead. The gravity-supplemen ing means in ludes lso thesec ndary xp llin means-or fing r I11, adap ed to enact with nlat olfisandsee cured to ,the closure, together with yvl iichjt may be moved axially of the receptacle.

Referring to fi igures "1 and 2, the terminalpart 2| is provided, in the fi ger-adjoinin .end 20 55 -thereof, with a finger-accommodating slot L9,

whose function is to permit the quickly effected withdrawal of part 2| along the abruptly curved end edge of the finger from the hole-containing sections of the walls of the section and of the closure, whereby, when the receptacle is held axially vertical with the dispensing end in an underneath position, a limited mass of powder is allowed to drop down under the force of gravity for entrapment thereof in the space between part 2| and said hole-containing sections, the joint passage being still closed.

Thereupon, now referring to Figures 3 and 4, the receptacle is disposed in a substantially horizontal positionIwith said two holes underneath and with the place of deposit, for example the bristles of a toothbrush, underneath said holes. The closure I2 is now pushed toward the receptacle H to intermediate position bringing said two holes into transverse and consequently axial orcompletealinement. The part 2| is forced by the camlike action of the finger, in a, transversely outward direction and causing the previously-entrapped powder to 'be thereby forcibly expelled outwardly thru said joint passage now constituted by the two axially alined holes, and deposited as indicated by the group of five arrows onto said toothbrush bristles, neatly and completely without any waste and without resorting to shaking the receptacle. In practice, this stage of intermediate relationship is actually one of brief duration.

.Thereupon, as is shown in Figures 5 and 6, the continued inward movement of the closure brings the parts into said relationship of ex- ;treme'retraction, wherein the opening M has figures, it will be'noted that the closure is provided with. a therefrom angled extension,-

functioning as a detent in that when in the relationship of-full extension, it abuts the tapering wall of section HB, and thereby restrains the closure from its otherwise possible further movement away from section I iB.

lTheexpelling plate 55 is shown in only one of several methods of attachment to thebody of the receptacle. It may be supported by a plu- 'rality of arms. Itmaybe secured by soldering or frictional retention within a wall-joint of the body itself or otherwise. The expelling plate may be of non-resilient material and even hingedly attached and actuated by a positivecontrol type of ,camlike finger that controls the movement of the plate in both directions.

The section I I3 need not take the tapered form as shown. In both transverse form and transverse dimension, it may correspond to the main body I iA.

No attempt has been made to describe all of the possible embodiments of the instant invention' that can. and .will suggest themselves to persons skilled in the art. The embodiment described herein and illustrated in the accompanying drawing, has been selected by me as 'a' practical and typical one sufiicing to set forth the principles of the invention, whose true scope is set forth in the hereto appended claims.
